I love this shirt! Here's a nice video from the actual designer about the process of making this shirt (including intentionally making it hard to OCR): https://youtu.be/jocGLiecpjU?t=526
Author here. Thank you so much for the link which I hadn't seen! I'm very happy to see this and I'm gratified that it was deliberately difficult to OCR, not just me.
It would probably be quicker to type it in than figure out how to OCR it. It would be like typing in a game from a COMPUTE! magazine 45 years go.
